Palmatine-loaded electrospun poly(ε-caprolactone)/gelatin nanofibrous scaffolds accelerate wound healing and inhibit hypertrophic scar formation in a rabbit ear model.

Hypertrophic scar (HS) has been considered as a great concern for patients and a challenging problem for clinicians as it can cause functional debility, cosmetic disfigurement and psychological trauma. Although many methods have been developed to prevent and treat HS, the scarless healing is still a worldwide medical problem. In this study, palmatine-loaded poly(-caprolactone)/gelatin nanofibrous scaffolds (PCL/GE/PALs) were fabricated by electrospinning, and their effects on wound healing and HS formation were investigated.
